Longcruise, I have a box of 180 Partitions and have wondered if the 30-30 would push 'em fast enough to make em open. Have you done any experimenting along this course, or seen any real results? I like the SST because of the trajectory. It gives me a point blank range of 200 yards, which is absolutely perfect for my hunting conditions, I don't have shot opportunities past 200 yards. But a 180 if it would open up quick enough would put a hurt on a whitetail.
